This document summarizes a research poster about designing an SDN-manageable hardware switch. The researchers built a fully OpenFlow-controlled switch using a multi-port hardware development platform running Linux and Open vSwitch. They tested its performance under real-world network conditions. Their goals were to enable higher network programmability and wider adoption of SDN in physical networks, as existing SDN devices are too expensive. The switch used a Soekris net4801 board with 6 Ethernet ports and 1 controller port. Tests showed bandwidth, datapath type impacts, CPU usage, and controller round-trip times. This provided a tool for future SDN development work.

Abstract
Abstract
Useful links and key points
Useful links and key points
Nowadays, SDN is mostly used
in virtual environments.
Hardware prices make them
absent in physical networks.
We have built a fully OpenFlow-
controlled switch and tested its
performance in real-world
network conditions.
We need hardware devices controllable by SDN
controllers in order to fully utilize SDN’s full potential.
Lack of affordable SDN devices is preventing massive
integration of SDN technologies.
OVS driven hardware routers do not provide great
performance due to CPU bound limitations.
